Functions Called by ordinalgmifs Functions, Not by the User

Description

These functions are called my other ordinalgmifs functions and are not intended to be directly called by the user.

Details

The du.adjcat, du.bcr, du.cum, du.fcr, and du.stereo functions calculate the derivatives at the current step for the adjacent category, backward CR, cumulative link, forward CR, and stereotype logit models, respectively, are used to identify which penalized parameter is updated. The fn.acat, fn.bcr, fn.cum, fn.fcr, and fn.stereo are the log-likelihood functions for the adjacent category, backward CR, cumulative link, forward CR, and stereotype logit models, respectively, are used to estimate the thresholds and non-penalized subset parameters (if included) at each step of the algorithm. The G function returns the probability for the indicated link function. The gradient function returns the gradient of the log-likelihood for the cumulative link models and is used for the cumulative link constrained optimization.

Value

these functions are called for intermediate results used internally by user-invoked functions
